ab224637 staining SOX17 in wild-type HeLa cells (top panel) and SOX17 knockout HeLa cells (ab265744) (bottom panel). The cells were fixed with 4% paraformaldehyde (10 min) then permeabilized with 0.1% Triton X-100 for 5 minutes and then blocked with 1% BSA/10% normal goat serum/0.3M glycine in 0.1% PBS-Tween for 1h. The cells were then incubated with ab224637 at 0.2μg/ml concentration and ab7291 (Mouse monoclonal to alpha Tubulin) at 1/1000 dilution overnight at 4°C followed by a further incubation at room temperature for 1h with a goat secondary antibody to rabbit IgG (Alexa Fluor^® 488) (ab150081) at 2 μg/ml (shown in green) and a goat secondary antibody to mouse IgG (Alexa Fluor^® 594) (ab150120) at 2 μg/ml (shown in red). Nuclear DNA was labelled in blue with DAPI.
Image was taken with a confocal microscope (Leica-Microsystems TCS SP8).

Western blot - Anti-SOX17 antibody [EPR20684] (AB224637)

Lanes 1-3 : Merged signal (red and green). Green - ab224637 observed at 51 kDa. Red - loading control ab8245 observed at 36 kDa.

ab224637 Anti-SOX17 antibody [EPR20684] was shown to specifically react with SOX17 in wild-type HeLa cells. Loss of signal was observed when knockout cell line ab265744 (knockout cell lysate ab257697) was used. Wild-type and SOX17 knockout samples were subjected to SDS-PAGE. ab224637 and Anti-GAPDH antibody [6C5] - Loading Control (ab8245) were incubated at room temperature for 2.5 hours at 1 in 1000 dilution and 1 in 20000 dilution respectively. Blots were developed with Goat anti-Rabbit IgG H&L (IRDye^® 800CW) preadsorbed (ab216773) and Goat anti-Mouse IgG H&L (IRDye^® 680RD) preadsorbed (ab216776) secondary antibodies at 1 in 20000 dilution for 1 hour at room temperature before imaging.

Western blot - Anti-SOX17 antibody [EPR20684] (AB224637)

This blot was produced using 4-20% SDS-PAGE containing 15 μg of rat E14 embryo lysate per lane at 150V for 1hr before being transferred onto a 0.45 μm PVDF membrane at 75V for 1hr. The membrane was then blocked for 1hr using 5% NFDM/TBST, then incubated with ab224637 (1/500) at room temperature for 1hr. After being washed three times in TBST, the membrane was incubated with Peroxidase conjugated goat anti-rabbit IgG (H+L) (ab97051) at 1/20,000 dilution for 1hr at room temperature. The membrane was washed three times again. Then the signal was developed using the ECL technique.

ab224637 was stored at a range of temperatures (+4°C, +22°C, +37°C) for 1 week before being tested in WB. The image shows the band intensity remains relatively constant across all storage temperatures, demonstrating that antibody activity is not affected under these conditions. This data was generated as part of a structured antibody stability study supporting Abcam’s transition from cold‑chain to ambient shipping.
